WINDOW-SASH HOLDING Application filed May 20,

This invention relates to window sash holding and latching devices and has for its primary object the -provision, in a manner as hereinafter set forth, of a sash holding and latching device of a construction permitting either anupper or lower sash to be held atany desired open position without the use of sash weights and pulleys or supporting sticks, such as are at present in use.

Another object is the provision, in a inanncr as hereinafter set forth, of an improved sash holding and latching device adapted to hold either an upper or lower sash separately or together at any desired open position, and further having means whereby certain ofthe sashes may be secured at any point.

Another object of the invention is the provision, in a manner as hereinafter set forth, of 1 an improved sash holding and latching device providing locking means ooacting with sash supporting means, both latching and supporting means being operable from the'inside only of the window, to secure the sash in any desired position.

A still further and final object of the invention is the provision, in a manner as hereinafter set forth, of an improved sash holding and latching device of simple construction, adapted to be located within the frame of the window, so as to be out' of sight, easy of operation, noiseless in action, providing positive and secure latching and holding means, and inexpensive to manufacture and apply.

The invention will be best understood from a consideration of the following detailed description taken in connection with the accompanying drawings forming part of this specification, with the understanding that the invention is not confined to any strict conformity with the showing of the drawings, but may be changed and modified so long as such changes and modifications mark no material departure from the salient features of the invention as expressed in the appended claim.

Referring now to the drawings in detail, wherein like numerals of reference indicate corresponding parts throughout the several views shown, the front of the window casing is indicated at 1, the back at 2, and the inner side wall at3, against which the sides of the lower sash 4 and the upper sash 5 slide. The usual inner, intermediate, and outer beading strips 6, 7 and 8', respectively, run longitudinally of the inner side of the Window casing to separate and guide the upper and lower sashes 4; and 5. Each of the sashes 4; and 5 has formed in its sides longitudinally extending grooves 9 and 10, respectively, the purpose of which will become apparentas the de scription in the case proceeds.

The device embodying this invention comprises a pair of casings 11 and 12, respectively, each having a removable cover 13' and 14 secured upon its face by means of screws15. Each ofthe casings 11' and 12 further has extended from one side an open casing 16 and 17, respectively, these open casings being of less widththan the outer casings as is clearly shown in Figure 3 of the drawings. The outer corners of each of the casings 16 and 17 is thickened between the side walls of the casings and there is formed therethrough an aperture for. the passage of a securing screw 18 which securing screws are of sufficient lengthto extend through the casing and engage the support upon which the casing is carried. The screws 15 which serve to retain the covers 13 and 14 upon tliecasings 11 and 12 may also be of sufiicient length to extend through the body of the caslng and into the support which carries the device.

As is clearly shown in Figures 2 and 4 the casing 13 and the open casing 16 are substantially twice as large as the casings 14 and 17 as this casing 13 contains a pair of bolt elements whereas the casing 14 contains only one bolt element. The side wall of the casing 11 has formed therethrough a pair of apertures and the intermediate wall 19 which separates the casing 11 from the easing 16 also has a pair of apertures therethrough and each of these apertures is in alignment with an aperture in the outer wall of the casing.

The side wall of the casing 12 also has formed therethrough an aperture for the passage of a bolt, and the wall 20 which divides the casing 12 from the casing 17 also has a corresponding aperture therethrough in alignment with the aperture in the outer wall of the casing. Each of the cover plates 13 and 14 has apertures therethrough, the cover plate 13 having a pair of apertures 21, each of which, when the plate 13 is in position, is in the same plane as the apertures through the side walls of the casing, and the cover plate 14 of the casing 12 has the aperture 22 therethrough which when the cover plate is in position is in the same plane as the apertures in the side walls of the casing 12.

The casing 11 has a pair of bolt members 23 and 24 having their rear ends extending through the apertures in the side walls of the casing, and the casing 12 has a single bolt 25 having its rear portion extending through the apertures in its side walls as shown in Figure 2, and each of the bolts 23, 24 and 25 has formed therein longitudinally extending slots 23, 24, and 25, each of these slots being of greater length than the diameter of the openings 21 and 22, and each being positioned in front of one of the said apertures.

The forward or free end of one of the bolts of the double casing, here indicated as the lower bolt 24, is finished off square as shown in Figure 2, and the other bolt of the double casing and the bolt in the single casing are bevelled at their free ends and from the-under side outwardly as indicated at 26 and 27. The rear or inner end of each of the bolts 23, 24 and 25, which extends through the inner or partitioning wall of each of the casings is provided with a longitudinally extending bore 28, 29 and 30 respectively, the bore of each bolt opening from the end thereof into the open casing at its rear.

The outer wall of the casing 16 has formed upon its inner side a pair of lugs 31 and 32, and the outer wall of the open casing 17 has formed upon its inner side a lug 33, and

surrounding and supported at one end upon each of these lugs 31, 32 and 33 is a spiral spring 34, 35 and 36, respectively, each of which has its forward end projected into the longitudinal bore in the inner end of the bolt adjacent thereto.

The casings 11 and 12 are placed within the window casing adjacent the inner face of the inner side walls 3 of the casing, and the double casing 11 is positioned at the upper end of and in alignment with the lower sash 4, and the single casing 12 is positioned at the lower end of and in alignment with the upper sash 5. It is apparent that the double casing 11 will be positioned forwardly of the single casing 12 and suitable supportin means is provided therefor in the form of a supporting block 36, the lower portion of the block being of greater width than the upper portion, and the double casing 11 is secured against the face of the lower portion of the block and the single casing 12 rests upon the ledge 37 formed in the face of the block and is secured against the face of the constricted upper portion as is clearly shown in Figure 4. This block is secured upon the inner face of the back 2 ofthe window casing.

The inner side 3 of the window casing has formed therethrough a series of passages 38, 39 and 40, each passage having extended therethrough one of the bolt members as shown in Figure 2, and each bolt member is of suflicient length to project a shortdistance beyond the outer face of the inner casing member 3.

The front side 1 of the window casing also has a series of vertically positioned apertures therethrough as indicated at 41, 42 and 43, and these apertures are so positioned as to be in alignment with the apertures 21 and 22 in the casing covers 13 and 14. The lower aperture 41 is elongated vertically as indicated in Figure 4, and the purpose of this will be presently disclosed.

Adapted to be positioned against the outer face of the face 1 of the window casing is a plate member 44 having vertically aligned openings 45, 46 and 47 therethrough, and

further having beneath the lower opening 1 45, a vertical slot 48, and this casing when in position against the face of the window casing will have the apertures therethrough in corresponding alignment with the apertures 41, 42 and 43 through the fare of the window casing. Screw holes 49 are formed in the plate for the passage of screws 50 for securing the plate in position.

Extending through the apertures in the plate 44 and in the face 1 of the window casing is a series of reciprocating pins 51, 52 and 53, each carrying at its inner end a flat pointed head 51, 52 and 53, which head is preferably made removable from the pin, and is adapted to extend throughv sion of the spring at its rear. when the re i-iprocating rod is forced inwardly. As is clearly seen in Figure 3 the slots 23, 24 and 25, are normally forward of the opening in the cover plate adjacent thereto, only the rear part of the slot extending over the opening. The point of the head extending through the opening inthe cover plate is adjacent the rear wall of the slot and when the head is forced inwardly the sloping face of the head will engage the rear wall of the slot and sliding thereagainst will draw the bolt backwardly compressing the spring at the rear portion thereof.

Each of the reciprocable shafts 51, 52 and 53 has upon its outer end a head 54, 55 and 56, respectively, the outer end of the rod 51 being constructed to form the annular recess 57 at the inner end of the head 54.

Extending through each of the rods is a cotter pin 58, and surrounding the rods and positioned between the cotter pin and the cover plate through which the rod projects are springs 59, 60 and 61, respectively. It may be seen that when the rods are forced inwardly to retract any one of the bolts, the spring surrounding the rod is compressed and when the rod is released the spring will expand and draw the rod outwardly away from the bolt, allowing the spring connected with the back of the rod to force the bolt forward again.

Slidable vertically upon the face of the plate 44 and positioned over the slot 48 is a locking finger 62. the upper end of which is bevelledas at 63' and the lower end is turned outwardly at right angles as at 64. Headed pins 65 are secured in the back of the finger 62 and extend through the slot 48 and the heads of these pins bear against the inner side of the plate 44 and slidably secure the finger 62 thereto. Extending inwardly through the slot 48 from the finger 62 is a downturned pin 66 which pin engages one end of a spring 67 the other end of which spring is hooked over the rod 51. When the rod 51 is pressed inwardly to draw back the bolt 24, which is here shown as a locking bolt, the finger 62 is automatically drawn upward by the spring 67 to engage in the recess 57 and thus hold the rod 51 in position. Upon drawing down the finger 62 to disengage the end thereof from the recess 57 the spring 59 will force the rod 51 outwardly to release the locking bolt 24.

Located in the groove 9, in the side of each window sash, is a rack bar 68, in the lower sasho and 69 in the upper sash. These rack bars extend the full length-of the sashes and are engaged'by the bolts23, 24 and 25.

In the operation of this device, should it be desired to raise the lower sash, the pin 51 is pressed inwardly until the finger 62 automatically engages in the recess 57 to hold the pin in the pressed-in position. This withdraws the locking bolt 24 from engagement with; the rack bar 68. It is then only necessary to lift the sash 4, as the teeth of the rack bar will engage the under or bevelled side 26 of the bolt 23 and force the bolt in to allow for the passage of the teeth. Vhen the sash has been raised to the desired height it is released and the bolt 23 will automatically project itself into engagement with the rack bar thus holding the window in released position. It is desired to lock the sash in this position, the finger 62 may be drawn downwardly to allow the spring 59 to force the rod 51 outward to release the locking bolt 24 which will be projected inwardly by the action of' "the spring 34 to engage in the rack bar in which the bolt 23 is engaged. When desiring to lower the sash, the rod 51 is pressed inwardly until engaged by the finger 62 as before explained to release the lock bolt 24. Then the rod 52 is forced inwardly to roject its head 52 into the slot 23 in the bolt 23 to withdraw the bolt from engagement with the lock bar whereupon the window will drop. When the rod 52 is released it will be withdrawn from engagement with the bolt 23 and the spring 35 will project the bolt 23 inwardly again to engage the rack bar 68 and the finger 62 may then be drawn downwardly to release the rod 51 whereupon the locking bolt 24 will again engage the rack bar 68 to lock the lower sas In Figure 6 of the drawings, there is shown a slight modification, this modification involving the lower bolt member and the position assumed. by the center bolt member. In this view, the lower bolt 70 is bevelled at the under side at its forward end as at 71, and the center bolt 72 is bevelled upon the upper side and at the forward end as at 73, instead of being bevelled at the under side as in the other form. In this form, the bolt 72 acts as the locking bolt to prevent the window from being raised and it is necessaryto retract this bolt before the window can be raised, and the lower bolt 70 acts as a support to hold the window open and must be retracted before the window can be closed, in the same manner as the bolt 23 in the otherform.

Having thus described my invention what I claim is:

A device of the character described, comprising a casing having a bolt element slidably held therein and adapted for engagement with the sash of a Window, said bolt being longitudinally slotted, means normally forcing the bolt to engaging position, a plunger element adapted to extend through the face of a Window frame and slidably mounted in the casing at right angles to the path of travel of said bolt, a cam head upon the inner end of said plunger Working in the slot against one Wall thereof to retract said bolt, said plunger further having an annular recess therein outside of said frame,

a spring element surrounding said plunger plunger, and a spring member acting uponv said latch to cause the same to move into engagement in said annular recess to lock the plunger 1n bolt retracting posltlon.

In testimony whereof, I afiix my signature hereto.
